WebIn CVX, functions are categorized in two attributes: curvature (constant, affine, convex, or concave) and monotonicity (nondecreasing, nonincreasing, or nonmonotonic). Curvature … WebJul 6, 2024 · A CVX file is a drawing file created by various Canvas GFX applications, such as Canvas X Draw (Windows version only) and Canvas X Geo, programs used to create …
CVX. Disciplined convex programming error: Invalid constraint: {complex ...
WebOct 10, 2010 · abs(total) >= P,but the window show me :Invalid constraint: {convex} >= {real affine} I don't know how to modify it,can anyone help me?because the constraint does write the total in the code has to be larger than P WebNov 29, 2024 · In the event this error is occurring due to a CVX bug, you can try rewriting your code (still using rel_entr) and see whether the error still occurs. For instance, objective = 0; for i = 1:N, objective = objective -rel_entr (... ; end; maximize (objective) . guoxiao_yin November 29, 2024, 2:14pm 3 Hi Mark,Thanks you for your reply. famous food in venice

WebMay 31, 2024 · Based on " Cvx real affine expression (1x2x2 array)" appearing in the title of your question, I presume J evaluates to 1 by 2 by 2, which is not a scalar, which it needs to be in order to be used as the objective. Also, you calculate W_hat but don’t use it, at least in the code that is shown. cvx May 31, 2024, 7:04pm 3 Thanks WebCVX recognizes that sqrt is concave and f'*x is affine, so it concludes that sqrt(f'*x) is concave. Now consider the second term min(4,1.3-norm(A*x-b)). CVX recognizes that min is concave and increasing, so it can accept concave arguments. CVX recognizes that 1.3-norm(A*x-b) is concave, since it is the difference of a constant and a convex ... WebMar 24, 2024 · That expression should be affine. I opened an issue trace_mpower (matrix,1) returns concave expression instead of affine at the CVXQUAD GitHub site. There really is no point to using CVXQUAD’s trace_mpower with an exponent of 1. You can instead just use trace: trace (A_n*W) ans = cvx real affine expression (scalar) coping skills for anger adolescents
